Ruffled hair, a lose shoestring

He's just misguided I think
Nina is describing the troubled youth, my opinion is he's one of those grunge/punk type of kids.
The ruffled hair, the nose ring. You don't see a lot of average white guys with nose piercings.
"He's just misguided I think"
Nina seems to think that he's astray of the "right" or "normal" path in life, seemingly going how own way, and doing his own thing, like drinking, smoking, rebelling in a sense and that is frowned upon by society.
